JR I bought a new 6 litre silverado 4X4 new body style, my girlfriend bought a new avalance 4X4 with a 5.3 litre and I have on order a new 07 C6... Does my Ease diagnostics need any updates to scan all 3 and who should I use to down load my scans when U finish tweaking them LS2 is going to charge me atleast another 300.00 dollars for each Vin and then some for a new version I assume... What do U recomend I do to get all these tuned so I can return them to stock the easiest and back to performance tune after any service work??? Thx...
